There are over 100 species of wild grapes that are known under a number of names-- 'Frost Grape,' 'River Grape,' 'Spanish Grape' (the term 'wild grape' will be used, too, covering all species)... The varieties presented here have extremely healthy leaves. They are easy to care for and are particularly suited for decorative purposes; they create a 'grapevine-ambience' without the high maintenance. They won't develop fruit (grapes), so their unfavourable side-effects -- wasps, birds and their excrement, mildew, etc..-- are not an issue here!
Vitis riparia, Vitis berlandieri (Frost Grape, River Grape, Spanish Grape)
They need a sunny (full sun) to (semi-)shaded location; they will develop more intense yellow autumn colours in the sun. Distance between plants: 2.5 - 5 metres. Available all year in pots, and in April / May as rootstock.
This is a climber with tendrils (no adhesive pads as with some other creepers), vigorous growth, yearly growth up to 2 - 4 metres; it may also cascade like a bridal train. Foliage from May to October. Has inconspicuous green-yellow flowers in early summer, insignificant or no fruit at all. Advantage: problems which can occur in ripening and ripe (wine-) grapes are avoided. Summer and winter prune as needed to restrain the vigorous growth habit and to prevent the plants from becoming scraggly. Best trained as cordons with spur pruning like for the wine grape.
Compatible with rods, trellises, pergolas, and arbours. Wires or (wire) ropes are especially recommended to attach the old sturdy stems. Stem formation and training similar to illustrations for the normal grapevine. For suitable wire rope systems, see below. Choose one within the easy or medium range.
